This App is approaching a full stop landing February 2016 with the launch of the new EASA FTLs. Until then it is available for free. My new app 'EASA vs Airline FTL' has hit the app store. It has been rewritten from scratch, it's universal (now for iPad too!) with many major improvements. It also supports EU-OPS, so it is of use for you from now on. Please read about details there. Please click on the developer's name (Alexander Flohr) or search for 'EASA vs Airline' Thank you for using my EU-OPS apps until now, they will continue to be supported until April/2016.
